Interview: Iain de Caestecker, star of Filth and Marvel's Agents of SHIELD

The Scottish actor also featured in Not Another Happy Ending in 2013

To say Scottish actor Iain de Caestecker had a good 2013 is a bit of an understatement. 'You don't notice it as much when you're in amongst it but like anything you do I try to make myself aware that there are tens of thousands of people that are just as capable or more capable of doing it than I am, so you have to keep reminding yourself how lucky you are,' explains de Caestecker.

And if you missed any of de Caestecker's big screen outings now is the perfect time to catch up as Not Another Happy Ending hits DVD. Starring Karen Gillan this breezy romcom also closed last year's Edinburgh International Film Festival. 'I played Roddy who was designed to be the comic relief,' adds de Caestecker.

'The origin of the show is tied into the movies but we're also trying to establish ourselves as characters in our own right, even though we are heavily based within the Marvel world we still want to be a standalone show. Obviously we're a few episodes ahead than where you are on TV and there's some really exciting stuff coming up and I'm excited to see how people react.'

Tom (De Caestecker) and Lucy (Englert) are a new couple driving to a festival in Ireland, but they get lost – and then things start to happen. Director Lovering didn't tell his stars what would happen next, so their fear and uncertainty is real, and despite the story's inevitable turn towards obviousness it's an…
